| Summary: | The spindle serves as a liaison between the drive and the tool or workpiece. There
are several parameters that influence in meeting the needs of machine tools when designing
a spindle, one of which is stiffness which greatly affects the accuracy and precision of a
machine tool.
The concept of parametric design is a concept that is used to produce machine tool
designs with different dimensions just by changing a few variables so that it can shorten the
time in redesigning a machine tool. The parametric design of the spindle is carried out to
produce variations of the spindle design.
Stacking Tolerance analysis is used as an analytical medium in the search for the
best variation of each geometric tolerance that will affect the performance of a spindle based
on the recommended standard. Geometric specifications in designing the spindle of the
Okuma-Howa ACT3 CNC lathe according to ISO 13041–1, including standard testing of
radial runout spindle bore.
Parametric design and stacking tolerance analysis were performed on the spindle of
a CNC lathe by making the parametric model and combining with the stacking tolerance
model. After all done, the result is an application of prototype parametric design, with the
hope of facilitating the user in varying the CNC lathe spindle. |
